Description

  The present invention relates to information presentation, and more particularly, to an information presentation system, an information presentation apparatus, and a program for presenting information to support the progress of a conference.

  In recent years, with the improvement of the accuracy of speech recognition technology, a technology that uses computers to extract predefined words from human speech and presents information related to predefined words to the person who speaks has become widespread. I am doing.

  For example, Japanese Patent Laying-Open No. 2005-215726 (Patent Document 1) discloses an information presentation system for performing information presentation using voice recognition. The information presentation system of Patent Document 1 includes a voice input unit that inputs a speaker's utterance voice, an action data storage unit that stores a condition corresponding to a predetermined keyword and action information related thereto, and information Presenting processing means is included. The information presentation processing means performs speech recognition processing of the uttered speech, detects the stored keyword from the processing result, and performs processing based on the corresponding action information when the detected keyword satisfies the above-described condition. Run.

  In relation to assisting in making adjustments for consensus building and mutual discussions at conferences and meetings, Japanese Patent Laid-Open No. 2011-015881 (Patent Document 2) A conference progress support device for the purpose of supporting the management of a conference is disclosed. The conference progress support apparatus of Patent Document 2 includes a conference information storage unit that stores information representing each agenda of the conference and information representing each participant of the conference, and information representing the start and end of the participant's remarks on the agenda. A speech information acquisition unit acquired via an input device, a progress management unit, and a speech status presentation unit. In response to the acquisition of the information indicating the start of the speech, the progress management unit conferences the agenda, the participant, the start time when the information indicating the start of the speech is acquired, and the progress information associated with the elapsed time from the start time. Further stored in the information storage unit. At the same time, the progress management unit measures elapsed time and updates the progress information until acquiring information indicating the end of the speech. The speech status presentation unit presents information representing the speech status of each participant for each agenda based on the progress information stored in the conference information storage unit.

  However, in the prior art disclosed in Patent Document 1 that presents information using the above-described voice recognition technology, when it is applied to a conference or the like, the information presenting situation cannot be taken into account, and thus information is presented when information presentation is unnecessary. In some cases, information is not properly presented depending on the situation. Therefore, there was a concern that unnecessary information presentation may diminish the user's consciousness from the agenda that should be directed to, such as diminishing the effect of the information presentation itself or derailing the discussion sideways. . The prior art of the above-mentioned Patent Document 2 is to present information representing the speech status of each participant for each agenda, and is capable of detecting a scene and presenting appropriate information according to the scene. There wasn't.

  The present invention has been made in view of the insufficiency of the above-described prior art, and the present invention provides a conference information processing system for enabling information to be presented at an appropriate timing according to a scene in a conference. An object of the present invention is to provide a conference information processing apparatus and a program.

  Hereinafter, although embodiment of this invention is described, embodiment of this invention is not limited to embodiment described below.

[First Embodiment]
In the first embodiment described below, as an example of the information presentation apparatus and the information presentation system, a projector apparatus having an information presentation function for supporting the progress of a conference will be described. FIG. 1 is a diagram showing a network environment 100 in which a projector apparatus 110 according to the first embodiment is arranged. A network environment 100 illustrated in FIG. 1 includes one or more client terminals 108 and a projector device 110 that are connected to each other via a network 102.

  The network 102 is configured as a wired or wireless intra-organizational LAN (Local Area Network), for example, and is connected to the global Internet 104 via a router (not shown). A network 102 shown in FIG. 1 is further connected to a document management server 106 that manages documents existing in the organization. The Internet 104 and the document management server 106 provide an information source for presenting information in this embodiment.

  The client terminal 108 outputs a screen for projection onto the screen to the projector device 110. The client terminal 108 also transmits various instructions to the projector device 110 via the network 102 in accordance with an operation input from the operator. The client terminal 108 is not particularly limited, but is portable information such as a desktop or laptop personal computer, a general-purpose computer device such as a workstation, a tablet terminal, a smartphone terminal, or a PDA (Personal Digital Assistant) terminal. It can be configured as a terminal or the like.

  The projector device 110 projects a screen input from a predetermined client terminal 108 on a screen. In addition, the projector device 110 executes various processes in response to various instruction inputs transmitted from the client terminal 108 via the network 102 according to an operation by the operator, and returns a process result. In a specific embodiment, the projector device 110 has a web server function, and various operation screens for an operator to instruct the projector device 110 in response to a request from a web browser on the client terminal 108. Respond to the web page. Projector apparatus 110 receives requests transmitted from a web browser in response to operations performed via various operation screens, and accepts various instruction inputs.

  Note that video output performed from the predetermined client terminal 108 to the projector device 110 is not limited to the LAN connection via the network 102 described above. Video output may be performed via a video output port such as DVI (Digital Visual Interface) or HDMI (High-Definition Multimedia Interface).

  The projector apparatus 110 according to the present embodiment further includes an information presentation function for applying information according to a recognized utterance by applying a voice recognition technology. On the other hand, when such an information presentation function is applied to a meeting, if information is presented regardless of the scene, there is a possibility that an ongoing discussion will be hindered. In addition, if information is frequently presented in response to remarks during a meeting, it may cause annoying experience for participants in the meeting or the effect of information presentation experienced by the participants may be diminished. This is also a concern.

  Therefore, the projector device 110 according to the present embodiment includes an information presentation function that determines a meeting scene and outputs appropriate presentation information according to the scene. Hereinafter, the information presentation function according to the scene in the first embodiment will be described in detail with reference to FIGS.

  FIG. 2 is a diagram showing a functional block 200 realized on the projector device 110 according to the first embodiment. 2 includes a conference state determination unit 204, a conference meta information management unit 206, a conference state determination learning unit 210, a conference state change action execution unit 212, a display output unit 214, and related information search. Unit 216, voice input unit 218, voice recognition unit 220, operation UI (user interface) unit 222, conference state change input unit 224, conference state change action input unit 226, and conference state determination rule management unit 228. The projector device 110 further includes a conference state determination rule table 202 for determining a meeting scene and conference meta information 208 describing the content of the conference such as the content of a statement as a data structure.

  The conference state determination unit 204 acquires the stored conference meta information 208 and compares the rules defined in the conference state determination rule table 202 with a condition (hereinafter referred to as a conference) for detecting a specific scene of the conference. It is referred to as a state change condition). The meeting state change condition is predefined to invoke an information presentation action that acts to change the state of the meeting depending on the particular scene observed in the meeting.

  In the present embodiment, the meeting scene when information is presented is determined based on the meeting state and the contents of the meeting that occurred in the meeting state. The conference state is context information expressing the degree of activeness and inactivity of the conference and is not particularly limited, but “active state”, “cooked state”, “normal state”, “dead state” ”And“ a state deviated to a side road ”and the like. For example, when it is detected that there is no speech for a while as the content of the conference when the conference state is “dead state”, it is considered that the discussion is stuck and no opinion is given. By presenting information in such a situation, it can be expected that the state of the conference will be improved from “stuck state” to “active state”, “normal state”, and the like.

  The conference state determination unit 204 detects a specific scene suitable for information presentation according to the conference state change condition, determines an action for presenting information, and requests the conference state change action execution unit 212 to execute it. The determination can be performed, for example, at a timing when a new description is made in the conference meta information 208.

  Note that the rules for detecting a specific scene of a conference and presenting information can be manually defined in advance by the vendor or the user. Although details will be described later, the conference state determination learning unit 210 determines a rule by a learning process based on the content of the conference in the conference meta information 208 given as teacher information, the state of the conference, and history information of the executed action. It may be generated.

  The meeting meta information management unit 206 records meta information describing the contents of the meeting in the meeting meta information 208 in response to input of external information such as voice input from a participant via a microphone. The content of the conference, which will be described in detail later, can include the content of a statement, the above-described change in the conference state, the action performed, and the like. In response to the new meta information being described and the conference meta information 208 being updated, the conference meta information management unit 206 notifies the conference state determination unit 204 to that effect. The meeting meta information management unit 206 also reads out and provides the meeting meta information 208 in response to an acquisition request for the meeting meta information 208 from the meeting state determination unit 204.

  When the conference state determination unit 204 determines that one of the conference state change conditions is satisfied, the conference state change action execution unit 212 performs an action associated with the condition (hereinafter, a conference state change action, or simply, This action is executed in response to a request to execute the action. After executing the requested action, the conference state change action execution unit 212 notifies the conference meta information management unit 206 of the execution of the action and records it as meta information.

  In the present embodiment, the conference state change action refers to an information presentation process that is expected to promote improvement of the conference state for consensus formation or mutual understanding at the conference. There are no particular restrictions on the conference state change action, but "message display prompting rest", "speech text display", "frequency search keyword Internet search result display", "frequent keyword search within document management system" Examples include “result display”, “text or image display for brightening the atmosphere”, and the like.

  The display output unit 214 projects the screen input from the client terminal 108 onto the screen, and projects the execution result onto the screen in response to the action execution of the conference state change action execution unit 212. According to the above-described example, “message display prompting rest”, “speech text display”, “frequent keyword Internet search result display”, “frequent keyword search result display in document management system”, “lighten atmosphere” "Text or image display" is projected onto the screen. The execution result can be displayed, for example, as a dialog or popup on a part of the currently displayed screen, displayed on the entire screen for a certain period, or displayed as a screen saver.

  The related information search unit 216 is called by the conference state change action execution unit 212 when an action for presenting an information search result is selected. The related information search unit 216 searches the information source such as the Internet 104 or the document management server 106 based on the search query corresponding to the content of the conference, and returns the obtained information search result to the display output unit 214. For example, when the action of “display frequently searched keyword search results in the Internet” or “display frequently searched keyword search result in document management system” is selected, a query including a predetermined keyword frequently used in a meeting is used. The information is retrieved from the Internet 104 or the document management server 106, and the retrieval result is acquired. Frequent words and frequent contexts can be obtained by applying natural language processing to a predetermined range of statements in the meeting meta information 208 and counting the words and contexts.

  The audio input unit 218 receives an input of an audio signal input via an audio input device such as a sound collection microphone connected to the projector apparatus 110, a microphone or a headset for each participant, for example. The speech recognition unit 220 performs speech recognition (SR: Speech Recognition) processing on the speech signal input to the speech input unit 218, converts the speech into text based on the speech input, and sends the message content (speech recognition) to the conference meta information management unit 206. Text). In addition, the voice recognition unit 220 detects a silent state from the input voice signal, measures the silent period, and causes the conference meta information management unit 206 to record it as a silent event.

  The content of the speech can be recorded by identifying the speaker and associating it with the speaker. The method for identifying a speaker is not particularly limited, but when a voice input device is distributed to each participant, it can be identified by the device identifier or the client identifier to which the device is connected. . In another embodiment, the speaker device 110 is notified via the client terminal operated by the speaker that the speaker himself speaks before speaking, or the participant in charge of recording the minutes is Identification may be made by inputting information about the speaker to the projector device 110 via the client terminal at the timing when the speaker speaks. Furthermore, in another embodiment, a speaker may be recognized from mixed speech by speaker recognition technology.

  The operation UI unit 222 is implemented as a web server function, for example, and responds to various operation screens to the client terminal 108 in response to a request from a web browser on the client terminal 108. Examples of the various operation screens include a conference state determination rule management screen for managing the above-described conference state determination rules, a conference state change input screen, and a conference state change action instruction screen. Here, the conference state change input screen is a screen for notifying the projector device 110 of the change in the conference state felt by the participants of the conference. The conference state change action instruction screen is a screen for instructing the projector device 110 to perform a conference state change action according to the conference scene felt by the participant. The operation UI unit 222 receives a request transmitted from a web browser based on operations performed via various operation screens, and distributes processing according to the operation screens.

  When an operation for notifying the changed conference state is performed via the conference state change input screen, the operation UI unit 222 instructs the conference state change input unit 224 to include the conference state after the change. Input state change instructions. The conference state change input unit 224 receives this instruction input, and causes the conference meta information management unit 206 to record the conference state after the change as meta information.

  When an operation for notifying an action execution instruction is performed via the conference state change action instruction screen, the operation UI unit 222 instructs the conference state change action input unit 226 to include the instructed action. Enter the change action execution instruction. The conference state change action input unit 226 receives this instruction input and makes an execution request for the instructed action to the conference state change action execution unit 212. The conference state change action execution unit 212 executes a specified action in response to an explicit action execution instruction by the operator of the client terminal 108, and then executes the action to the conference meta information management unit 206. Notify and record as meta information.

  In this way, the conference meta information management unit 206 associates the information for identifying the conference, the utterance content (speech recognition text) by the voice recognition unit 220, the speaker, the uttered start time, and the end time. At the same time, it is recorded in the conference meta information 208. In addition, when an instruction to change the conference state is input, the conference meta information management unit 206 records the detected person, the changed conference state, and the changed time in the conference meta information 208. . When the conference state change action is executed, the conference meta information management unit 206 further describes the execution instructor, the executed conference state change action, and the executed time in association with each other.

  The meta information based on the instruction input made to the conference state change input unit 224 and the conference state change action input unit 226 described above is used by the conference state determination learning unit 210 as teacher data input from the conference participants. Is done. The conference state determination learning unit 210 acquires the meta information in the conference meta information 208 and learns in which context the change from which conference state to which conference state is recognized. The conference state determination learning unit 210 also learns which conference state change action has been executed in what context based on the conference meta information 208. Through the learning process, a new condition for presenting information corresponding to the meeting scene is extracted, and a rule is added to the meeting state determination rule table 202. The learning process can be performed, for example, at the timing when the meeting meta information 208 is updated. The details of the learning process executed by the conference state determination learning unit 210 will be described later.

  The conference state determination rule management unit 228 is a means provided for manually defining a rule in the rule table 202 or correcting or deleting a rule added by the conference state determination learning unit 210. When an operation is performed via the conference state determination rule management screen, the operation UI unit 222 inputs an instruction including the operation content to the conference state determination rule management unit 228. The conference state determination rule management unit 228 edits the content of the rule table 202 based on the passed operation content. Details of the management processing of the rule table 202 by the conference state determination rule management unit 228 will be described later.

  In a specific embodiment, the projector device 110 may further include a questionnaire input unit 230 and a report output unit 232. In response to a request from the web browser on the client terminal 108, the operation UI unit 222 can respond a questionnaire screen and a report screen as operation screens.

  When a conference evaluation input operation is performed via the questionnaire screen, the operation UI unit 222 inputs an instruction including an evaluation result by the participant to the questionnaire input unit 230. The questionnaire input unit 230 acquires an evaluation result performed by the conference participant on the conference based on the operation content, and causes the conference meta information management unit 206 to record the questionnaire result.

  When an operation is performed via the report output screen, the operation UI unit 222 inputs an instruction including the operation content to the report output unit 232. Based on the operation content, the report output unit 232 acquires meta information related to the conference status and questionnaire results from the conference meta information management unit 206, totals the conference status and evaluation, and outputs a report including the total results. To do. The operation UI unit 222 receives the total result, embeds the total result in the display data, and responds to the client terminal 108.

  Hereinafter, a process for learning rules to be added to the conference state determination rule table 202 while collecting the conference meta information 208 will be described with reference to FIGS. FIG. 3 is a flowchart showing a learning process executed by the projector device 110 according to the first embodiment. The process shown in FIG. 3 is started from step S100 in response to the projector device 110 being set to the learning mode and instructed to start the conference. In step S101, the process is branched according to the type of information input from the conference participants.

  If voice data corresponding to the participant's speech is input in step S101, the process branches to step S102. In step S102, the speech recognition unit 220 converts the speech data from the speech input unit 218 into text and generates speech recognition text. In step S103, the conference meta information management unit 206 records the speech event with the identified speech, the start time and end time of the speech as a set, using the speech recognition text as the speech content, and loops the process to step S101. Let

  FIG. 4 is a diagram illustrating a data structure of conference meta information 250 recorded by the conference meta information management unit 206. The meeting meta information 250 shown in FIG. 4 is data described in XML (Extensible Markup Language), and is stored in, for example, an XML database for each meeting. The significance of element tags and attributes in the meeting meta information 250 is as shown in Table 1.

  In the data structure shown in FIG. 4, in line 004-007, the remark element tag indicates that the speaker is “taro”, and a statement with the content “XXX University Management Preparatory Meeting ...” It is recorded with the start time and end time. Lines 008-010, 011-013, and 014-016 are also speech events.

  If silence audio data is input in step S101, the process branches to step S104. In step S <b> 104, the voice recognition unit 220 detects the silent period from the voice data from the voice input unit 218. In step S105, when the detected silent period is equal to or longer than the predetermined time, the conference meta information management unit 206 determines the detector (here, the system), the start time and the end time of the silent period for the silent period. Is set to record a silent event, and the process loops to step S101. The silent period may not be specified in the meeting meta information 250. This is because the duration of the utterance is recorded with the Remark element tag in the conference meta information 250 shown in FIG. 4, so that a period other than the utterance event may be treated as a silent period.

  On the other hand, if an instruction is input via the operation UI unit 222 in step S101, the process branches to another processing flow. FIG. 5 is a diagram illustrating a UI screen provided from the operation UI unit 222 and displayed on the display device of the client terminal 108 in the first embodiment. FIG. 5A is a diagram illustrating a conference state change input screen 300. The conference state change input screen 300 shown in FIG. 5A specifies a message display 302 for prompting input of the conference state after the change, a conference state display 304 indicating the state of the conference so far, and the conference state after the change. The buttons 306a to 306e associated with each conference state. When any of the buttons 306 a to 306 e is clicked on the conference state change input screen 300, a conference state change instruction including the conference state corresponding to the button 306 is input. As described above, this instruction input indicates a change in the conference state that is sensed by the conference participants and notified to the projector device 110.

  If a conference state change instruction input is input from the client terminal 108 in step S101, the process branches to step S106. In step S <b> 106, the conference state change input unit 224 receives an instruction input from the client terminal 108 via the operation UI unit 222. In step S107, in response to the input of the conference state change instruction, the conference meta-information management unit 206 records the changed new conference state, the detected person, and the detected time as a conference state change event. The detector can be identified using the identifier of the client terminal of the instruction input source.

  Lines 017 to 019 in the conference meta information 250 shown in FIG. 4 record a conference state change event that changes to a “stuck state” by assuming that the detector is “Ken” by the State element tag. The conference state change event may be detected by the system as shown in lines 001-003.

  In step S108, the conference state determination learning unit 210 acquires the conference meta information 208 from the conference meta information management unit 206, and learns using the state change event by the participant as teacher data. More specifically, the conference state determination learning unit 210 extracts, from the acquired conference meta information 208, in which context the conference state is changed to which conference state. In step S109, the conference state determination learning unit 210 adds the rule to the rule table 202 by associating the conference state before the change and the extracted condition with the new conference state after the change. The rules extracted in step S108 and added in step S109 will be described together with the description when the conference state change action instruction is input.

  FIG. 5B is a diagram illustrating a conference state change action instruction screen 310. The conference state change action instruction screen 310 shown in FIG. 5B includes a message display 312 that prompts input of an action to be executed, and buttons 314a to 314e corresponding to the actions. The button 314e is a button associated with an action for presenting information on the result of searching for frequent departure words, and the instruction screen 310 further includes UI components 316 to 320 for inputting parameters for executing the action.

  The pull-down menu list 316 is a UI component that specifies which period of frequent departure words is included in the search query. A radio button 318 is a UI component for selecting whether a frequent word search unit is a frequent word or a frequent context. The radio button 320 is a button for designating whether to select “Internet” or “in-house document management server” as an information source. When any one of the buttons 314a to 314e is clicked on the conference state change input screen 300, a conference state change action instruction including an action corresponding to the button is performed.

  If a conference state change action instruction input is input in step S101, the process branches to step S110. In step S <b> 110, the conference state change action input unit 226 receives a conference state change action execution instruction input from the client terminal 108 via the operation UI unit 222. In step S111, the conference state change action execution unit 212 executes an action in response to a request from the conference state change action input unit 226, and responds with completion of the execution. In step S112, the conference meta information management unit 206 records the executed action, the executor, and the executed time as a set as an action execution event. The executor can be identified using the identifier of the client terminal that has transmitted the instruction input.

  In the data structure shown in FIG. 4, in line 020-022, it is assumed that the action is “Ken” by the Action element tag, and the action of “message display prompting break” is displayed together with the time when the execution instruction is given. Action execution events are recorded.

  In step S113, the conference state determination learning unit 210 acquires the conference meta information 208 from the conference meta information management unit 206, and extracts from the conference meta information which conference state change action has been executed in what context. To do. In step S <b> 114, the conference state determination learning unit 210 adds a new rule to the conference state determination rule table 202 by associating the current conference state and the extracted condition with the action input.

  On the other hand, if an instruction input for ending the conference is input in step S101, the process branches to step S115, and the learning process is terminated.

  Hereinafter, the rules for determining the meeting scene and calling the action will be described in more detail. FIG. 6A is a diagram illustrating a data structure of the conference state determination rule table 260 in the first embodiment. As shown in FIG. 6A, the conference state determination rule table 260 includes a current state, a condition item applied to the conference meta information in the current state, a corresponding conference state change action, a priority, Includes columns where the number of occurrences and the number of effects are entered. The current conference state and condition items constitute a conference state change condition for detecting a specific scene of the conference based on the context.

  Numbers 1 to 5 in the conference state determination rule table 260 shown in FIG. 6 (A) indicate that when the conference state is “stuck state”, a silent period (SilentTime) of 300 seconds or more is detected, and the discussion is stuck. Corresponds to a meeting state change condition that is detected as a scene where no opinion is given. As described above, the conference state referred to by the rule determination may be a conference state input from a participant, or may be a conference state detected by the system based on the rule.

  In the example shown in FIG. 6 (A), “message display prompting rest”, “remark text display”, “Internet search”, “document management server search”, and “brighten atmosphere” with respect to this meeting state change condition. A plurality of actions such as “display image” are associated with each other. A priority is set for each action, and this priority is used to calculate a probability of which action to select when the meeting state change condition is satisfied. In the example shown in FIG. 6A, 100, 90, 80, 70, and 60 are set as priorities for numbers 1 to 5 that are the same conference state change condition, respectively. Then, an action is selected with a probability defined by a value with the total value 400 as a denominator and each priority as a numerator. For example, in the first rule, the occurrence probability is 25%. When the meeting state change condition is satisfied in the rule determination described later, one of the rules numbered 1 to 5 is selected with the above probability based on random number generation.

  The number of occurrences is a count of the number of times that the action has occurred in the context. Here, the number of occurrences of the action based on the instruction input from the participant is mainly counted. Therefore, a large number of occurrences means that the participant has often felt the necessity of action in the context, and means that there is a high probability of being an effective rule. The number of effects is counted up when the state of the meeting is improved after the action, and it means that there is a high probability that this is an effective rule. Judgment of whether the conference state has improved is based on the notification of explicit conference state change from the participant or the detection of the rule-based state change in the direction of the positive transition defined between the states in advance. This can be done by determining whether it has changed. The above priority may be manually set on the conference status determination rule management screen by the participant confirming the number of occurrences and the number of effects, or automatically determined by the system according to the number of occurrences and the number of effects Adjustments to the values may be made.

  Table 2 below exemplifies conditions that can be entered in the condition items.

  As illustrated in Table 2, the condition items are a threshold condition item for silent time (first condition example), and a threshold condition item for the frequency of occurrence of a predetermined specific word (second condition example). , A threshold condition item for the frequency of occurrence of a predetermined specific context (third condition example), a condition item that a specific speaker has spoken (fourth condition example), and a specific statement content Condition item (fifth and seventh condition examples), condition item not including specific utterance content, threshold condition item (sixth condition example) for the time when the same speaker continuously speaks, specific From the group consisting of threshold condition items for the time when the person is not speaking continuously, threshold condition items for the elapsed time (seventh condition example), threshold condition items for the ratio (statistical value) of the silent time to the speaking time Selected It was can include at least one condition item. In addition, these condition items may be used alone, or a plurality of condition items may be combined by logical sum or logical product, or may be combined in order.

  FIG. 7 is a diagram for explaining the rule learning process of the conference state determination learning unit 210 in the first embodiment. FIGS. 7A and 7B exemplify parts 280 and 284 of the meeting meta information and rules 282 and 286 extracted from the parts, respectively. First, when a conference state change action execution event is recorded in step S112 in FIG. 3, the conference state determination learning unit 210 determines a context from the conference meta information 208 in step S113. In context determination, the most recent conference state at the time when the conference state change action execution event is recorded is extracted, and a plurality of events that are a predetermined number of times or a predetermined time from immediately before the time when the execution event is recorded Condition items are extracted from.

  In the example shown in FIG. 7A, the conference state change event in the rows 101-103 is detected to detect the conference state “dead state”, the silent event in the rows 105-106 is detected, and the condition item “SilentTime> 120 "is extracted. Then, the recorded conference state change action “message for prompting a break” is generated in association with the extracted conference state and condition items and added to the conference state determination rule table 202.

  In the example shown in FIG. 7B, the conference state change event in the row 201-203 is detected, and the conference state “dead state” is detected. And the utterance event on lines 204-206 is detected, and there is no “Speaker = master AND Remark =” opinion that fits the predefined dictionary? A condition item related to the utterance “” is extracted, a silent event in lines 207 to 208 is detected, and a condition item “SilentTime> 60” is extracted. Here, the master value for the Speaker attribute is the role of the chairman as the role of the participant, and is a modification of the condition item for the participant. Then, the recorded conference state change action “action for prompting a break” is generated in association with the extracted conference state and condition items.

  In the example shown in FIG. 7B, based on the previous event, based on the single rule for the condition item “SilentTime> 60” and multiple events going back, the condition item “Speaker = master AND Remark =” There is no opinion. ? "" And a rule that combines the condition items "SilentTime> 60" in order. Extraction of such condition items can be performed using a pattern dictionary that is predefined on the vendor side or user side, and which rule is generated or both rules are generated depends on the pattern. Can be predefined with a dictionary.

  FIG. 6B is a diagram illustrating a data structure of another conference state determination rule table 270 according to the first embodiment. The table 260 shown in FIG. 6A associates the conference state change action with the conference state change condition. On the other hand, FIG. 6B shows a rule for detecting a change in the conference state that associates a new conference state with the conference state change condition. As shown in FIG. 6B, the conference state determination rule table 270 is input with the current state, the condition items to be applied to the conference meta information in the current state, the associated new conference state, and the number of occurrences. Column to be processed. A new conference state means transition to this state when a predetermined condition item is satisfied in the predetermined conference state, and the transition of the conference state can be considered as a kind of conference state change action.

  The condition items are the same as described above. For example, in the example of FIG. 6B, the first rule is that in the conference state “normal state”, the silent state lasts for 60 seconds, and then the master (master) A rule for detecting a change to “stuck state” by detecting the utterance of “who?” Is shown. The second rule is a rule for detecting a change to the “active state” when the ratio of the silent state is less than 20% in the conference state “normal state”. Such extraction of rule condition items for detecting a change in conference state can also be performed using a pattern dictionary that is predefined on the vendor side or on the user side.

  Hereinafter, with reference to FIG. 8 and FIG. 9, the process which manages a meeting state determination rule is demonstrated. FIG. 8 is a diagram illustrating a conference state determination rule management screen 330 provided from the operation UI unit 222 and displayed on the display device of the client terminal 108. The conference state determination rule management screen 330 shown in FIG. 8 is used to correct or delete a rule manually input by a user or added by a learning process by the conference state determination learning unit 210, and to add a new rule. It is a screen. The management screen 330 includes a table 332, a correction button 334, a delete button 336, an add button 338, a recommended rule display button 340, and a close button 342. The table 322 includes a record for each rule including the current state, condition items, conference state change action, priority, and number of occurrences.

  When a record is selected on the table 332 and the correction button 334 is clicked, a dialog for editing the selected rule is displayed. When a record is selected on the table 332 and the delete button 336 is clicked, the selected rule is deleted from the conference state determination rule table 202. When the add button 338 is clicked, a dialog for adding a new rule is displayed.

  In addition, since the rules added by the learning process of the meeting state determination learning unit 210 are extracted from the meeting meta information 208 by using a dictionary pattern, the rules are not necessarily composed of only valid rules, and many similar rules are added. Can be done. The recommended rule display button 340 is a button for calling up a dialog for organizing and aggregating such rules.

  FIG. 9 is a diagram illustrating a recommended rule display screen 350 that is called when the recommended rule display button 340 is clicked on the conference state determination rule management screen 350. The recommended rule display screen 350 shown in FIG. 9 includes a table 352, a reflection button 354, and a return button 356. The table 352 includes a record for each aggregated rule including the current state, condition items, conference state change action, priority, and number of occurrences. A check box 352a of the table 352 is a UI component for designating whether to validate or invalidate the candidate rule.

  As a calculation method of the aggregated rules, a calculation process is performed in which condition items in the grouped conditions are aggregated by grouping under the same or similar conditions (previous conference state and condition items). For example, for a numerical condition such as a threshold condition item for a silent period (SilientTime), an average value of the numerical values can be calculated and aggregated. If it is a condition item that includes a specific word or context (speaking content) or a condition item that a specific speaker speaks, the rule ignores words, contexts, and speakers that appear less frequently, It can be aggregated to leave only high words, context and speakers. As a result of aggregation, when a plurality of actions are associated with the same meeting state change condition, the actions are ranked in descending order of occurrence frequency.

  In the example of FIG. 9, the threshold condition item for the silent period (SilentTime) in the rules 1 to 5 shown in FIG. 6A and the rule added thereafter is calculated as 270 seconds as the average value of the numerical values. And the condition item “SilentTime> 270”. Then, five actions are ranked by the number of occurrences and associated with the condition item “SilentTime> 270”.

  As described above, the rules of the conference state determination rule table 202 referred to in the determination are defined through the rule extraction by the conference state determination learning unit 210 and the aggregation and editing of the rules by the conference state determination rule management screen 330. .

  Hereinafter, a process of presenting information according to a meeting scene based on the prepared meeting state determination rule table 202 while collecting the meeting meta information 208 will be described with reference to FIGS. 10 and 11. FIG. 10 is a flowchart illustrating an information presentation process corresponding to a scene executed by the projector device 110 according to the first embodiment. The process shown in FIG. 10 is started from step S200 in response to, for example, the projector device 110 being set to the information presentation mode and instructed to start a conference. In step S201, the process branches according to the type of information input from the conference participants.

  If audio data corresponding to the participant's speech is input in step S201, the process branches to step S202. In step S202, the voice recognition unit 220 converts the voice data from the voice input unit 218 into text, and in step S203, the conference meta information management unit 206 records a speech event, and the process proceeds to step S211. The processing after step S211 will be described later.

  If silence audio data is input in step S201, the process branches to step S204. In step S204, the voice recognition unit 220 detects the silent period from the voice data. In step S205, the conference meta information management unit 206 records the silent event, and the process proceeds to step S211.

  On the other hand, if a conference state change instruction input is input from the client terminal 108 in step S201, the process branches to step S206. This instruction input indicates a change in the conference state that the participant of the conference has felt and explicitly notified through the conference state change input screen 300 described above. In step S206, the conference state change input unit 224 receives a conference state change instruction input from the client terminal 108, and in step S207, the conference meta information management unit 206 records it as a conference state change event.

  If a conference state change action instruction input is input in step S201, the process branches to step S208. In step S <b> 208, the conference state change action input unit 226 receives a conference state change action execution instruction input from the client terminal 108. In step S209, the conference state change action execution unit 212 executes a conference state change action. In step S210, the meeting meta information management unit 206 records the action execution event.

  When the process proceeds from step S203, step S205, step S207, and step S210 to step S211, in step S211, the conference state determination unit 204 determines whether or not the conference state change condition is satisfied. Note that the rule determined here may include a rule for changing the conference state as shown in FIG. If it is determined that none of the meeting state change conditions is satisfied (NO), the process loops again to step S201 and waits for the next event. On the other hand, if it is determined that any of the rules in the conference state determination rule table 202 is satisfied (YES), the process proceeds to step S212.

  In step S212, the conference state determination unit 204 selects a conference state change action associated with the matched conference state change condition, and requests the conference state change action execution unit 212 to execute it. Here, when a plurality of rules are matched, an action is selected with a probability corresponding to the above-described priority. In step S213, the conference state change action execution unit 212 executes a conference state change action.

  FIG. 11 is a diagram illustrating an information presentation screen projected on the screen by the display output unit 214 based on the action execution by the conference state change action execution unit 212 in the first embodiment. FIG. 11A illustrates the action execution results of “message display prompting rest” or “text or image display for brightening the atmosphere”. FIG. 11B exemplifies the action execution result of “speech text display” that collectively displays past utterances. FIG. 11C exemplifies action execution results of “display frequently searched keyword internet search results” to “display frequently searched keyword search results in document management system”.

  Referring to FIG. 10 again, in step S214, the conference meta information management unit 206 records the executed conference change action, the executor, and the time as a set as a conference state change action execution event, and loops again to step S201. . Here, when the rule for changing the conference state as shown in FIG. 6B is met, the change in the conference state is recorded. On the other hand, if an instruction input for ending the conference is input in step S201, the process branches to step S215 to end the present information presentation process.

  Hereinafter, the questionnaire collection process and the report output process according to the present embodiment will be described with reference to FIGS. 12 and 13. FIG. 12 is a diagram illustrating a questionnaire screen displayed on the display device of the client terminal. The questionnaire screen 360 includes a message display 362 and buttons 364a to 364c for inputting an evaluation for the conference. When a conference evaluation input operation is performed via the questionnaire screen, the questionnaire input unit 230 acquires an evaluation result from each participant corresponding to the clicked button 364, and the conference meta information management unit 206. The questionnaire results are recorded.

  FIG. 13 is a diagram illustrating a report screen displayed on the display device of the client terminal. FIG. 13A shows a report screen in which a change in the ratio in each conference state in which a change is detected or a change is input by a participant is displayed as a graph by day. A report screen 370 shown in FIG. 13A includes a graph display 372, a button 374 for switching the transition to a monthly display, a button 376 for switching the transition to a weekly display, and a transition to the daily display. Button 378.

  FIG. 13 (B) shows a report screen that graphically displays the transition of the distribution of conference evaluations input by participants. The report screen 380 shown in FIG. 13B is a graph display 382, a button 384 for switching the transition to a monthly display, a button 386 for switching the transition to a weekly display, and a switch for switching the transition to a daily display. Button 388. With the report output shown in FIG. 13, the conference participants can check whether the conference content history based on the conference meta information describing the content of the conference is consistent with the evaluation of the conference subjectively felt by the participants. Can be recognized.

  According to the first embodiment described above, the necessity of information presentation is determined from the stored conference meta information 208 in light of the rules in the predefined conference state determination rule table 202. Therefore, it is possible to present information that can be expected to improve the conference state according to a specific scene of the conference. In addition, since information presentation is performed after a specific scene of the meeting is determined, the effect of the information presentation itself may be diminished, and the user's consciousness can be originally directed, such as derailing the discussion sideways It can be expected that the shift from the agenda should be reduced.
